Given numbers are 404,101,787,284,961
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 404,101,787,284,961 is 21693909988.
Find LCM of 404,101,787,284,961 with Prime Factorization
| 2 | 404, 101, 787, 284, 961 |
| 2 | 202, 101, 787, 142, 961 |
| 101 | 101, 101, 787, 71, 961 |
| 1, 1, 787, 71, 961 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 101 x 1 x 1 x 787 x 71 x 961 = 21693909988
Therefore, the lowest common multiple of 404,101,787,284,961 is 21693909988.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
404 x 101 x 787 x 284 x 961 = 8764339635152
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
404 : 1, 2, 4, 101, 202, 404
101 : 1, 101
787 : 1, 787
284 : 1, 2, 4, 71, 142, 284
961 : 1, 31, 961
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 404,101,787,284,961, is 1.
Now, the common factors can be found like this.
404:2x 2x 101
101:101
787:787
284:2x 2x 71
961:31x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 101 = 404
Therefore, the value for common factors is 404.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 8764339635152/(1x404)
LCM = 8764339635152/404
LCM = 21693909988
Thus, we can understand that the LCM of 404,101,787,284,961 is 21693909988.
